INTEGRAL STOP.

Application led November 4, 1919. Serial No. 335,683.

To all whom t may concern:

Be it known that we, PHILIP MUELLER and ANTON C. SCHUERMANN, citizens of the United States', residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Integral Stops, of which the following is a specification.

This invention relates to stops-for basin and other fittings, and has as its main obj ect to provide a fitting, which may be, as here shown, the inletor supply pipe leading to a cock or faucet, with an integral stop for cutting off or regulating the flow of water. Our integral stop is designed to take the place of the handle cocks now generally used, and which are objectionable in that they mar. the appearance of the fitting, or are located in some inaccessible place. Our improved stop may be placed in a fitting which connects the cock or faucet with the service pipe, so that access may be readily had thereto, and the appearance of the fitting is in no way mitigated against.

The construction of stop herein described is such that the removable parts of the stop may, for purposes of renewal or repair, be easily withdrawn from the basin tting without disassembling the several parts. The stop is very simple in construction, comprises a relatively small number of parts,

i and may be manufactured at a relatively low cost, the construction being such that the supply pipe together with the integral stop applied thereto may be sold as a single article of manufacture when so desired.

The above and other objects of our invention are obtained by the structure described in the following specification and illustrated in the accompanying drawings, and where- 1n Figure 1 is an elevational view of a basin cock and fitting, the latter being provided with our improved tintegral stop.

Figure 2 is a longitudinal sectional view through the fitting and stop shown in Fig- -ure 1.

Figure 3 is a perspective view of the several parts of which our improved stop is composed, these parts being showndisassembled. Figure 4 is a partial view of the fitting showin another form of integral stop applied t ereto.

Figure 5 is a longitudinal sectional view through a fitting having a regulating device and integral stop.

Figure 6 is a longitudinal section through an angle coupling showing our improved stop applied thereto.

Figure 7 is a view, similar to Figure 2, showing a slightly different embodiment of our invention.

Figure 8 is a sectional view showing our improved stop applied to a globe valve.

Referring to thel drawings by numerals, and particularly to Figures 1, 2 and 43, like characters representing similar parts in the several views, 10 designates a fitting having connected to the outer end thereof by means of a couplingy nut 11 a cook or faucet 12 which may be of any suitable or wellknown construction. Within the fitting 10, as will be seen from Figure 2, is an integral web or diaphragm 13, a portion of which extends longitudinally of the pipe, which portion is provided with a central circular opening having one edge suitably 4beveled to form a valve seat 14 through which water is 4adapted to pass to the cock.l

The wall of the fitting adjacent the seat is preferably flattened on itsouter surface to form a level surface and preferably, as here' shown, thickened inwardly to give a substantial valve mounting, such as will sustain the valve parts, and such thickenedlsection has an orifice 15 therethrough,the axial or'longitudinal center of said orifice being in alignment with the center of said seat 14. 16 designates a plug which, in the present embodiment, is substantially of the same external diameter throughout its length and the plug has an external thread complementary to the internal threads of the oriice 15, so that the plug may be screwed into place in said orifice. To permit turn-- ing of the Spanner plug 16, it is provided at yits outer end with a plurality of radial notches 17 forming suitable wrench holds for a Spanner wrench or the like. The Spanner plug 16 has a central longitudinal opening therethrough suitably threaded to receive complementary screw-threads 18 upon the lintermediate portion of a valve stem 1.9 carrying at its inner end a valve head 20 which may be Vof any suitable construction.A The outer end of the spanner plug 16, as will be seen from Figure 2, has an enlarged bore 21 internally screw-threaded and receiving a, washer or packing ring 22 which surrounds the unthreaded portion of the stem 19, the washer being forced tightly into place against the` shoulder at the inner end of the bore 21 to provide a Huid-tight joint between the stem and the plug by means of a packing nut 23 adapted to be screwed into said enlarged bore. The upper end of the stem 19 is polygonal or squared in shape for the reception of a suitable wrench or other tool for turning the stem to move the valve-head 2O to and from its seat as desired. 24 designates a closure cap preferably of the same material and having the same finish as the fitting to which it is applied, and this cap is internally threaded so that it may be screwed o-ver the outer end of the Spanner plug 16 tocover the stem and plug and give to the pipe a neat and pleasing appearance, and to prevent tampering with the stop valve. About the orifice 15 in the fitting 10 is an annulargroove adapted to receive a packing-ring or washer 25 against which the lower edge of the closure cap is adapted to be forced to form a fluid-tight joint between the plug and the fitting.

It is, of course, obvious that our invention may be applied to various forms of basin fittings and Ithat the speci-fic structure of the' stop may be more or less varied to suit the conditions under which it is to operate, and for purposes of illustration, we 'have shown in the accompanying` drawings, several embodiments of our invention which involve substantially thesame principles of construction as the .internal` stop shown in Figures 1 to 3.

In Figure 4, the construction of integral stop is very similar to that disclosed in Figure 2, except that the central opening through the spannerplug is of the same diameter throughout its length, no packing gland being provided between the stem and the plug, and the plug has, intermediate its ends, an external circumferential flange 26 which is adapted to engage in the bottom of the annular groove, in the fitting about the orifice v-15 to limit the inward movement of the spanner plug. This construction may be used where a verysimple plug is desired.

ln Figure 5, we have shown a fitting provided with an integral stop and a regulating device for cutting off and contro-lling the flow of water through the pipe, the regulating device and stop being, in the present instance, very similar in construction eX- cept for the val-ve members carried on the inner ends of the stems of the respect-ive de.; vices. The integral stop portion (shown om the left-side of the pipe in this figure) is very similar to the integral stops shown in Figures 2 and 4, differing only in proportion of the parts and in that the ,valvehead 27 is provided with a hole or passage 28 extending from the periphery to the proper direction. It will be. seen that when a full or unrestricted flow ofwater is desired through the fitting, the stems 19 and 30 of the stop and regulating devices are rotated in a direction to withdraw the valve head 27 and the needle valve 31 from each other,

and so permit water to flow freely over the valve-seat 14. When it is desired to restrict the How of water, the stem 19 of the integral stop is rotated, causing the valvehead 27 due to the threaded engagement between the stem and the plug 16, to move rfectilinearly and into engagement with the seat 14 and the control of water is then regulated, by advancing or withdrawing the needle valve 31 relative to the opening or seat 29. To shut off the flow of water completely through the pipe, the head 27 of the integral stop is brought to its seat 14 and the needle valve 31 ,is brought to its seat 29 in the head 27.

Referring to Figure 6, we have disclosed our improved stop applied to an angle coupling, the latter having a diaphragm 32 extending transversely across one of the branches of the through opening 32. At the elbow of the coupling, and in alignment with the inlet opening of the coupling is located the orifice 15 which receives the plug 16 to ether with the valve 20.

lin igure 7 ,the construction of integral stop is very similar to that shown in the preceding views. lt will be noted that in this figure, the inner end of the packing nut 23, that is the end which engages against the washer or packing 22, is somewhat conical in shape, so that the packing 22 is forced closely about the stem 19.

Figure 8 is a view quite similar to that shown in IFigure 6, but illustrates our improved stop as applied to a globe valve.

It will be seen that in each oth'e emf bodiments of our invention herein disclosed, our invention consists generally in providing a valve seat in the basin fitting, a spanner plug screwed into an orifice in the side of the fitting, and a stem ro-tatabij:

be quickly and readily turned to shut off' or regulate the flow of water, it being merely necessary to remove the closure capand apply a wrench to the upper end of the valve stem. The plug and valve stem, in the preferred form of our embodiment, together with the packing, may be removed from the orifice in their assembled `condition.

.While we have shown a particular c0n,

struction, it will be understood that varia` tions in mechanical details may be made without departing from the spirit of our invention, and we do not, therefore, limit ourselves to the exact details shown and described, except in so far as we are limited by the terms ofthe appended claims.
